The aim of this paper was to examine the influence of biostimulators, with or without the use of fungicides, on seed quality parameters and early growth of sunflower seedling. Testing was conducted at the Institute of Field and Vegetable Crops in Novi Sad on cytoplasmic male sterile sunflower line HA-26-PR. The experiment included six treatments: Slavol S (25%), Slavol S (25%) + fungicide (a.m. metalaxyl-M), Bioplant Flora (2%), Bioplant Flora (2%) + fungicide (a.m. metalaxyl-M), Slavol S (25%) + Bioplant Flora (2%), Slavol S (25%) + Bioplant Flora (2%) + fungicide (a. m. metalaxyl-M) and control. Results of the research showed that treating the seed with biostimulators prior to sowing has a significant influence on seed germination parameters and early growth of sunflower seedling. The individual application of fertilizers, with or without the use of fungicide, gave a positive effect, while their combination led to a negative effect. The individual application of fertilizers, with or without combination with fungicide, may increase germination energy by 5%, germinability by 6%, but may also reduce the time of seed germination. Likewise, their use has a positive effect on early growth of sunflower seedling.

And Storage

Using the standard method, we studied the germination energy of seed of seven different sunflower genotypes (five hybrids and two cytoplasmically male sterile female lines) developed at the Institute of Field and Vegetable Crops in Novi Sad. The seed was treated with the fungicides benomil, metalaxyl and fludioxonil and the insecticides thiamethoxam and imidacloprid and kept for a year in a storage facility. Analysis of variance showed that there were highly significant differences among the genotypes, chemical treatments, and storage periods. Highly significant differences were also recorded for all the interactions among the factors studied. On average, the highest germination energy was found in the hybrid H2 (93.45%), whose values of this parameter were highly significantly higher than those of the rest of the genotypes, except for the hybrid H1. Also, each of the hybrids had highly significantly higher germination energy than either of the two lines, and the differences among the hybrids themselves were highly significant. Looking at the chemical treatments, the control had the highest germination energy by a highly significant margin (80.39%). The largest difference was observed in relation to the treatments with insecticides (5.48 and 9.56%). These treatments had highly significantly lower values of germination energy than those involving fungicides. Germination energy increased in the first nine months of storage, peaking at 81.29%. After that, there was a sharp drop to 68.94% after 12 months of storing. Differences among the different storage periods were all highly significant except for that between six and nine months of storage, which was not statistically significant.

Field Emergence

Tomato is one of the most commonly growing vegetable crops among the farmers in Sri Lanka. Standard laboratory germination of tomato seeds fulfills the regulatory requirements of seed marketing. However, poor field performance is an overwhelming problem to farmers. Present study was focused on the longevity of two varieties of tomato seeds as affected by their quality characters (percentage germination, moisture, field emergence and vigour index, seed protein and carbohydrate contents) including seed health (exposure of Clavibacter michiganensis subsp. Michiganensis (CMMV), Spotted wilt virus (TSWV) and Leaf curly top virus (LCTV)) under four different storage environmental conditions during a one-year long storage study. Seeds were packed in triple-laminated aluminum packets (TLA) and stored in low temperature storage conditions (17±1 °C and 65% RH) and in ambient conditions in Gannoruwa, Kundasale, and MahaIlluppallama that represent the three agro-ecologically zones; Mid Country Wet Zone (MCWZ), Mid Country Intermediate Zone (MCIZ) and Low Country Dry Zone (LCDZ) respectively. Seed quality parameters displayed varied responses depending on the variety. Physiological changes that occur in seeds due to temperature, RH, changes in proteins and carbohydrate content, CMMV and TSWV during storage were manifested as reduction in seed germination, field emergence and vigour index. However, none of the seedling carried LCTV and therefore its effect on seed quality parameters could not be assessed. The seeds could be stored for ca. 29 months at low and constant temperatures and RH conditions without compromising local seed germination standards compared to ambient storage in the three environments. CMMV and TSWV detected in all seed samples indicated potential threats to tomato farmers in Sri Lanka.

This article is devoted to the studying hermeneutic circle in the development of methodological culture of future music teacher. Under the conditions of globalization processes, tendencies of convergence of world cultures improvement of culturological training of student youth requires new approaches, in particular, culturological training of students of pedagogical specialties. The task of pedagogical education is to develop a teacher as a specialist and as a person of high culture, who has a special positive effect on the personality of school student. This article analyses the works of scientists dedicated to the issues of establishment and development of the hermeneutic approach in philosophical, psychological, and logical and gnosiological contexts. It is defined the essence of the concept of “hermeneutic circle” as one of the basic principles of the hermeneutic approach. There have been provided the examples of interpretation of the principle of hermeneutic circle by various scientists. Hermeneutic approach is applied in sciences such as pedagogy, psychology, economics, sociology etc. In pedagogical science the hermeneutic approach at the level of conceptual use was elaborated by A. Zakirova. She introduced the term “pedagogical hermeneutics”. Hermeneutic circle as a principle of text understanding is based on the interrelation of the part and the whole. Understanding of the whole consists of the understanding of the individual parts, and understanding of the parts requires understanding of the whole. The concepts of the part and the whole are correlated: the text is a part concerning the whole creative activity of the author, which in its turn is a part of the particular genre or literature in general, as well as the part of spiritual life and biography of the author. The idea of hermeneutic circle means also that there is no understanding of the text without certain prerequisites: understanding is preceded by some idea of what is yet to understand. There have been determined the peculiarities of the use of the principle of hermeneutic circle in the development of methodological culture of the future teacher of musical art. In light of hermeneutical trends, the penetration of which in the realm of musical art can be traced quite clearly, the use of the hermeneutic circle principle in the development of methodological culture of the future teacher of musical art appears not only in the narrow interpretation of the particular phenomenon or group of phenomena, but much wider — as a means of learning and understanding of the worldview by a person.

Soybean production in the system of organic agriculture is not very demanding, and this has been well documented both through experimental results and commercial production. However, one of the biggest problems in organic production is the lack of adequate pre-sowing treatments. Therefore, the aim of this study was to examine the effect of the electrostatic field. This is a physical treatment that was first used for seed treatment in the 18th century but has mostly been neglected since then. Seeds of five soybean genotypes with differently colored seed coats (yellow, green, dark green, brown, and black) were included in this study. The seeds were exposed to different values of direct current (DC) with the following voltages: 0 V (control), 3 V, 6 V, and 9 V, to which the seeds were exposed for 0 min (control), 1 min, and 3 min. After exposing the seeds to the electric field, the physiological properties of seeds and seedlings at the first stage of growth were evaluated. The results show that the effect of the electrostatic field on seed quality depends on the genotype, voltage, and exposure time. The application of DC can be a suitable method for improving seed germination and the initial growth of soybean seedlings. In addition, the results indicate that it is necessary to adjust the DC treatment (voltage and duration of exposure of seeds) to particular genotypes since inadequate treatments may reduce the quality of seeds.

Objective:The Scripps neurologic rating scale (SNRS) is a summary measure of individual components comprising a neurological examination, designed for use in multiple sclerosis (MS). Our objective is to evaluate the responsiveness of the SNRS, within the context of a 2-year, randomized, double-blind crossover study of the efficacy of cladribine for treatment of secondary progressive MS.Methods:Effect sizes were determined for the SNRS and its components, separately for each treatment group (initial placebo, and initial cladribine) over both years of the clinical trial, using a standard random effects model.Results:Individual components tended to show positive effect sizes (improvement) during periods of active therapy in both treatment groups, and negative effect sizes (deterioration) during periods of no active therapy. Summation indices derived from the individual components of the SNRS seemed somewhat more stable than the individual components. The two components mentation and mood, and bladder, bowel, or sexual dysfunction, were rather unresponsive in our clinical trial.Conclusion:Changes in the components of the SNRS over the course of our clinical trial were consistent between the two treatment groups. Most components were moderately responsive; and, the summary SNRS score appropriately summarized the moderate magnitudes of change evinced in the individual components.
